描述

The 9DML4493A is a Gen1–7 compliant 4-input, 4-output clock multiplexer. It can also operate as a dual 2-input, 2-output clock multiplexer. It has very low additive phase jitter and is suitable for all PCIe data rates. The device supports today's complex system power sequencing requirements with Power Down Tolerant (PDT) and Flexible Power Sequencing (FPS) features.
